Skew line defects in graded materials

The interaction force between skew line defects (dislocations and/or line forces) in functionally graded, elastically anisotropic media is shown to be independent of the distance between them. Special cases are homogeneous infinite and semi-infinite media and bicrystals. The interaction force betwee...

Zusammenfassung:	The interaction force between skew line defects (dislocations and/or line forces) in functionally graded, elastically anisotropic media is shown to be independent of the distance between them. Special cases are homogeneous infinite and semi-infinite media and bicrystals. The interaction force between two skew dislocations in a plate with free surfaces is the same as in an infinite medium.
